Thanks, will check that. Need to add DeOxit to my shopping list. Where can it be found?

The MQX motors are too expensive, I am going to order 2 A and 2 B motors for the 929 since they are supposed to be identical. I know they plug in under the covers and they probably won't match so I'll need to mod the MQX to take these new motors. What have you guys done?

I'm having difficulty finding any replacement pinion gears.
Closest I've found aer wholesale lots of 3000 plastic gears with too large of a a bore (2mm).
I think the bore on these is <1mm .75mm to be exact.
Plastic/nylon with a tight fit would be ideal.
Rather than trying to get another brass part onto the used motors.
I have no idea how I'd get a new brass part on it without breaking the motor.

I think RTF TX has same range as a DX6i or similar range.
I'll check TX power next time I have access to an RTF TX.
It's probably going to be 50-100mW which will give you about the same range as the DX6i's 200mW on USA power setting.

No that's not correct. Not trying to cause any arguments but it has been confirmed on many of HH's products that use the rtf controller that the max range is 300 feet. I know it's a correct fact as many of us using it while flying their micro plane line have had it drop out on us right at that range level. You can't even compare the rtf transmitter range with the dx6i range. It's not remotely even in the same category. I had my champ drop out many times at around a 300 feet or less range while using the rtf tx, but flew it many, many times so far and high in the sky that it was a spec and took a while to try and even get it back to a place where I could even figure out what direction it was going. It was easily way over 1000 feet and never had it drop out once.

Nope no arguments :-)
I don't have/own any RTF TX devices.
Just purely out of curiosity I'll test the RF output power next time somebody brings one over :-)
Father in law has an RTF mQX I'll test this when I have a chance, and also do a side by side range comparison with my DX6i (sounds like this has been done before).
You never know what you'll shake out, different hardware version different range etc.
The DSM2 chips themselves put out ~4mW of power without an amplifier.
The DX6i most certainly uses an amplifier to get this up to 200mW.
The RTF TXs might just pull it right off the chip @4mW :-)

Would definitely like to hear your readings as it would be interesting to know. I just know what they say and what many of us have experienced, but even with that it would be cool to actually see the numbers and know the science behind it.

I'm hoping they have a little more power than the bare 4mW..
I noticed people are tearing the RF modules out of RTF transmitters and putting them into Turnigy 9Xs to get DSM2 functionality out of the T9X.
based on all that effort I was expecting some higher level of performance.
Will let you know when I test.

The developer got the mW mapped for the various module during the early development of the DSM2 mod. Including the startup 1's and 0's that set the bit for the power output to conform to each countries regulation if I recall correctly. So those smart fellers really covered a lot of the bases.

Putting a RTF module into a Turnigy radio will not magically make the range more. Without antenna mods, etc. What you gain is 2 additional channels and the programmability of it. In the end, it's still a parkflyer module. Remember, the RTF is MLP4DSM. Stands for Micro Low Power 4 channel DSM technology. It's considered a low power module and is great for the micro helis, micro quads that many of us fly.

Now, if you take the High Power modules from a HP6DSM, DX4e, DX5e...or even a DX6i...then you are going to have about the same range as those radios are rated for. HP6DSM stands for High Power 6ch DSM.

The module inside the HP6DSM is similar to the DX4e, DX5e and DX6i. With the newer revised version in those last three radio having DSMX capability. Which you also retain once inserted into the Turnigy 9x.

Putting a HP6DSM, DX4e or DX5e into the Turnigy makes sense because you gain the programmability and flexibility of the open source firmware. Plus many mCPX and nCPX owner already has the DX4e to hack up.
